K3 - configure RX/TX equalizer using macros

[Thomas Norff]

To all who are missing a easy way to configure the RX/TX equalizer.
Based on the available tools i would use the Macros to set the RX/TX
equalizer for different needs.

An short example (pls don't type in the comments...):

        AI0; no response
        K31; is needed to use the SWT command
        MN008; or 009 to select RX / TX equalizer
        SWT53; tab CLR => set all values to 0dB
        SWT11; tab A/B => select first frequency
       
                                11 A/B  (1) => select 50 Hz
                                12 REV  (2) => select 100 Hz
                                13 A>B  (3) => select 200 Hz
                                24 PRE  (4) => select 400 Hz
                                27 AGC  (5) => select 800 Hz
                                29 XFIL (6) => select 1200 Hz
                                33 NB   (7) => select 2400 Hz
                                34 NR   (8) => select 3200 Hz

        UP; to set +1 dB
            or up to 16 times each !!
        DN; to set -1 dB
        MN255; exit the menu
        K30; back to default (optional)
       

This one will set TX-EQ to -3/-2/0/0/0/+2/+3/+3  (this is only an example...
pls don't ask why....)

AI0;K31;MN009;SWT53;SWT11;DN;DN;DN;SWT12;DN;DN;SWT29;UP;UP;SWT33;UP;UP;UP;SW
T34;UP;UP;UP;MN255;K30;

I was just about to post comments about the implementation of the RX EQualiser when I came across Thomas's post below. I'm now using the elecraft k3 utility program (command tester) to hop quickly between RX EQ settings on the K3....brilliant, thanks! Here are some cw suggestions to try:

CW RX FLAT
AI0;K31;MN008;SWT53;MN255;K30;

CW RX 400Hz
AI0;K31;MN008;SWT53;SWT24;DN;DN;SWT27;UP;UP;UP;SWT29;DN;DN;DN;DN;DN;MN255;K30;

CW RX 1000Hz
AI0;K31;MN008;SWT53;SWT12;DN;DN;DN;SWT13;DN;DN;SWT24;DN;SWT27;UP;UP;UP;SWT29;DN;DN;DN;DN;DN;MN255;K30;

The 400/1000 (bandwidth) settings both peak the audio response for pitch settings in the 700-800Hz range and have the effect of 'brightening' any cw sig in that window. You can then switch back to FLAT to quickly compare the difference.

I mainly use CW and am interested in what RX EQ settings everyone else is using.
